If you really need recommendation, I would like to say you mine.
HOLD your ETH, and do not use them to buy anything else.
Please set your sell orders around $1000, that equals to $3000 in total.
Then, forget the order, forget about your ETH, but please remember your account on exchange, and its password, 2FA code to log in later.
Come back 2 years later, then you will see your sell orders filled up.

Invest into anything else hardly to help you get profits.
